IMPROVEMENT IN DRAIN-TILE MACHlNES.

Specification forming part of Letters Patent No. 116,668, dated .Iuly 4, lcl.

' ble others skilled in the art to make and use the same I will proceed to describe, referring to the drawing', in which the same letters indicate like parts.

The nature of this invention consists in arranging and securing a water or steam-cylinder, with a depressed chambered table-bed, firmly upon a timber or column for holding tile-molds firmly in position and in line with said steam-cylinder, the piston-rod of which is made hollow, the outer end of which is connected to a hollow plunger that works through, and is guided by and actuates a former and presser-collar located in a iianged recess or depression in the table-bed directly under the tile-matrix, so that, when the cement is packed into the mold in the common way, by imparting motion to the plunger through the medium of the water or steam-cylinder the cement will be firmly compressed into the mold, except a short distance from the bottom of the mold, which portion is completed by the continued action of theplunger in forcingthe guide and form ercollar along with it, thereby couipressing the lower portion of the cement into or within the dimensions of the mold, and, at the same time, heat or steam is allowed to enter the chamber of the plunger through the piston-rod, thereby par tially heating the inner surface of the cementing tile, and thereby providing for the more ready removal of the tile from the matrix.

In the accompanying drawing, Figuregl is a front sectional elevation.

A represents a wood or metal column, supported in a convenient position for use. B is a water or steam cylinder, constructed and operated, automatically or by hand, in the common way, and is formed on or firmly secured to the post A. C is a table-bed formed on or firmly secured to the post A the proper height from the door to render it convenient for the workmen. This table,

preferably, should be made of metal. It is provided with a chambered depression, D, of about the same diameter as the inside diameter of the matrix E. This chambered depression is also provided withudiange-seat,F. Intothis ehambered depression is fitted a plunger guide-joint former, Gr, which serves the purpose of guiding the plunger, and to form and compress the lower end of the tile within the dimensions of the matrix E. H is the plunger, one end being formed coneshaped, thc other end being connected to the piston-rod I of the steam-cylinder B. This plunger is made hollow, having a chamber, O, into which steam or heat is admitted through the orifice J in thc piston-rod I, the object of which is to partially set the cement while the plunger is pressingit into the mold. This mold or matrix is made and secured upon the table-bed in the common nay. The space between the matrix and plunger, shown by dotted lines, represents the thickness of the A cement through the body of the tile. H is a collar formed on the end of the plunger, the office of whichA is to lift the guide and former G and compress the cenient firmly within the longi` tudinal dimensions ofthe matrix. K is a disk arranged on. the pistoii-rochand connected to the former G by rods'L, the object of which (if it shall be found necessary) is to bring the former G back to its restingplace upon the flange F by the action of the iiangehead of the plunger, just asit is being fully withdrawn from the tile just formed in. the matrix.

I believe I have thus shown the nature and construction of this invention so as to enable others skilled in the art to make and use the same therefrom.
